I know what you’re getting at. It’s possibly hard to interpret cause break has so many possible meanings. I’d have to say that break in this case is referring more to the fact that his concentration broke and he hit the ball out than that he broke the rally. That’s how I see it anyway. It could really be seen either way =\

Yes, but I am asking if it was meant to be written in such a conflicting way. In the flow of the overall tennis match, Marou just broke to a score of 3-1, but Miyagawa broke in the sense that his rally failed first by going out. I was simply asking for a clarification if it was meant to be written in a confusing manner or if there was a mistake somewhere.

I’ll have to let Ruggia give you his opinion. Personally, I don’t see anything conflicting or confusing about it. Whether he worded it “messed up” or “broke,” if looking at it in a rally sense then it makes better sense to say he broke the rally rather than he messed it up.
